Add Constant.kind field

2019-03-12T18:03:38+00:00

The value is a string for string and byte literals, None otherwise.
It's 'u' for u... literals, 'b' for b... literals, '' for ... literals.

Remove d_initial from the parser as it is unused (GH-12212)

2019-03-09T15:35:50+00:00

d_initial, the first state of a particular DFA in the parser has always been initialized to 0 in the old pgen as well as the new pgen. As this value is not used and the first state of each DFA is assumed to be the first element in the array representing it, remove d_initial from the parser to reduce complexity.

bpo-33608: Make sure locks in the runtime are properly re-created. (gh-12245)

bpo-33608: Minor cleanup related to pending calls. (gh-12247)

Fix the Py_atomic_* macros. (#12240)

2019-03-08T19:06:56+00:00

The macros were working only because our usage happened to parse correctly.  Changing that usage (e.g. with pointers) would break the macros.  This fixes that.

bpo-35975: Support parsing earlier minor versions of Python 3 (GH-12086)

2019-03-07T20:38:08+00:00

This adds a `feature_version` flag to `ast.parse()` (documented) and `compile()` (hidden) that allow tweaking the parser to support older versions of the grammar. In particular if `feature_version` is 5 or 6, the hacks for the `async` and `await` keyword from PEP 492 are reinstated. (For 7 or higher, these are unconditionally treated as keywords, but they are still special tokens rather than `NAME` tokens that the parser driver recognizes.)

bpo-9566: Fix compiler warnings in gcmodule.c (GH-11010)

2019-03-06T16:54:12+00:00

Change PyDTrace_GC_DONE() argument type from int to Py_ssize_t.

bpo-36142: _PyPreConfig_Read() sets LC_CTYPE (GH-12188)

2019-03-06T00:44:31+00:00

* _PyPreConfig_Read() now sets temporarily LC_CTYPE to the user
  preferred locale, as _PyPreConfig_Write() will do permanentely.
* Fix _PyCoreConfig_Clear(): clear run_xxx attributes
* _Py_SetArgcArgv() doesn't have to be exported
* _PyCoreConfig_SetGlobalConfig() no longer applies preconfig

bpo-36142: Add _PyPreConfig_SetAllocator() (GH-12187)

2019-03-06T00:13:43+00:00

* _PyPreConfig_Write() now reallocates the pre-configuration with the
  new memory allocator.
* It is no longer needed to force the "default raw memory allocator"
  to clear pre-configuration and core configuration. Simplify the
  code.
* _PyPreConfig_Write() now does nothing if called after
  Py_Initialize(): no longer check if the allocator is the same.
* Remove _PyMem_GetDebugAllocatorsName(): dev mode sets again
  allocator to "debug".

bpo-36142: _PyPreConfig_Write() sets the allocator (GH-12186)

2019-03-05T23:36:56+00:00

* _PyPreConfig_Write() now sets the memory allocator.
* _PyPreConfig_Write() gets a return type: _PyInitError.
* _Py_InitializeCore() now reads and writes the pre-configuration
  (set the memory allocator, configure the locale) before reading and
  writing the core configuration.
